I recently turned my Dual Titan V1.1 into a single and re-flashed the firmware, but the bed-levelling routine isn't working the same. Instead of hitting 9 points and allowing me to fine-tune each, the head moves to the 4 corners and says it's done. Is there a more recent version, or a way to add proper mesh bed levelling to the firmware?

(In case there was any doubt: I'm a dweeb when it comes to electronics, which is why I decided to try to simplify my BB. So far it isn't going quite as planned. )
